The GPD rating of an ro filter designates the output of the ro filter in gallons per day. This is how all reverse osmosis filters are rated regarding size.
A 50 gpd ro filter produces 50 gallons of ro water in a 24 hour period under optimum conditions of water temperature and pressure. With age, the gpd output of an ro filter declines. When the ro membrane is exhausted it is inefficient and wasteful. Proper maintenance on a reverse osmosis filter includes regular replacement of the
prefilter cartridges which protect the membrane. This is especially important in high demand uses such as discus fish water changes or maintaining a large marine or reef fish room. Neglecting prefilter cartridge replacement results in premature ro membrane depletion. TFC stands for thin film composite. This type of membrane works on both well water and city municipal water supplies. TFC ro membranes require carbon prefilters to remove chlorine from the water. All reverse osmosis filters are manufactured with carbon prefilters and these should be changed regularly. Sediment prefilter cartridges should also be changed on a regular basis on all ro filters.
These tfc 50 gpd replacement ro membranes are some of the finest ro membranes on the market.
These ro membranes are manufactured by Dow. These ro membranes feature hi silicate removal. This ro membrane provides the soft, pure water desired for aquarium or drinking water use. These ro membranes are NSF certified and FDA approved for cooking and drinking water use. Filmtec membranes are made in the U.S. by Dow, the leader in reverse osmosis filter technology.
These ro membrane replacement filters fit any standard ten inch ro filter housings. Reverse osmosis filters use a standard size housing. This also allows easy upgrade. To increase the output of any ro filter, simply replace the ro membrane with
the desired size. Replace the flo restrictor to match and the ro filter is upgraded without purchasing a new filter unit. These membranes fit Osmotic, Spectrapure, Pinnacle, Barracuda, Dolphin, Stingray, you name it- this one fits it!!!
Rocky Mountain Discus Hatchery uses reverse osmosis water blended with tap water to produce soft water for discus fish breeder pairs. Discus fish breeders have a higher hatch rate when spawning in soft water. Hard water in a discus breeder tank hinders fertilization of the discus eggs. While non breeding discus fish do not require water parameters with a low ph and hardness, discus breeders do. Discus fish grow well in water with a medium level of hardness.
